记录别另一用户锁定
记录别另一用户锁定
1.查看数据库锁，诊断锁的来源及类型：
select object_id,session_id,locked_mode from v$locked_object;
2.找出数据库的serial#以备杀死;
select t2.username,t2.sid,t2.serial#,t2.logon_time from v$locked_object t1,v$session t2 where t1.session_id=t2.SID order by t2.LOGON_TIME;
3杀死该session:
alter system kill session 'sid,serial#';
